麻烦大家了，我都搞了一个月的打印模块了，接近崩溃的边缘了

我的这个函数enum系统的打印机
void CSetupPrint::EnumPrintertoBox()
{
DWORD cbPrinters;
DWORD cbNeeded, cReturned, j;
int i;
cbPrinters = 4096L;

if (!(gpPrinters = (PPRINTER_INFO_1)LocalAlloc((LMEM_FIXED | LMEM_ZEROINIT),
cbPrinters)))
{
OutputDebugString( "InitPrint: LocalAlloc for gpPrinters failed.");
return ;
}
if (!EnumPrinters(PRINTER_ENUM_LOCAL|PRINTER_ENUM_CONNECTIONS, NULL, 1, (LPBYTE)gpPrinters,
cbPrinters, &cbNeeded, &cReturned))
{
if (GetLastError() == ERROR_INSUFFICIENT_BUFFER)
{
LocalFree((LOCALHANDLE)gpPrinters);
gpPrinters = (PPRINTER_INFO_1)LocalAlloc((LMEM_FIXED | LMEM_ZEROINIT),
cbNeeded);
cbPrinters = cbNeeded;

if (!EnumPrinters(PRINTER_ENUM_LOCAL|PRINTER_ENUM_CONNECTIONS, NULL, 1, (LPBYTE)gpPrinters,
cbPrinters, &cbNeeded, &cReturned))
return;
}
}

gpszPrinterNames = (PSZ *)LocalAlloc((LMEM_FIXED | LMEM_ZEROINIT),
cReturned * (DWORD)sizeof(PSZ));

gpszDeviceNames = (PSZ *)LocalAlloc((LMEM_FIXED | LMEM_ZEROINIT),
cReturned * (DWORD)sizeof(PSZ));
j = cReturned;
for (i = 0; i < (INT) cReturned; i++)
{
j--;
CString strTemp = (LPSTR)gpPrinters[j].pName;
int index = m_ctlprinter.AddString(strTemp);
m_ctlprinter.SetItemData(index, i);
UpdateData(TRUE);
gpszPrinterNames[i] = gpPrinters[j].pName;
gpszDeviceNames[i] = gpPrinters[j].pDescription;
}
m_ctlprinter.SelectString(1,m_printer);//系统缺省的打印机
}


其中CComboBox m_ctlprinter;
extern PPRINTER_INFO_1 gpPrinters;
extern PSZ *gpszPrinterNames;
extern PSZ *gpszDeviceNames;
#include <winspool.h>
#include <drivinit.h>
